Nathan Thomas has joined Shrewsbury Town on loan until the end of the season.
The deal was signed on transfer deadline day with the attacking player likely to go straight into the League One challengers' team for the weekend's encounter at Bristol Rovers. He was one of the players highlighted for a possible departure by Chris Wilder this month.
Thomas was signed from Hartlepool United in the summer for an undisclosed fee but has made just three appearances for the Blades this season.
The 23-year-old did score on his last appearance for United, in the Emirates FA Cup at Ipswich Town.
